Having a separate promo code and an invite code is a bit inconvenient...
If I want to invite someone to Neat, I have to give them an invite code, and then also later on give them the promo code. That's kind of weird, if you have a chance to make it into a single code that the user will enter at sign up, that would be easier for new users.
(Of course, if someone wants to get an extra $50, feel free to use my promo code REF2xw50 )
We don't use invite codes anymore, so if the user downloads the latest version of the app it won't ask for invite. You'll only need the referral code.
We should have made it a bit more clear probably!
